Pesticides are an important part of an Integrated Pest Managment (IPM) plan. The areas treated are often shared by pollinators like bees, butterflies, wasps, and some birds and bats. Pollinators are essential in the survival and propogation of many flowering plants both in farms and on the urban landscape. As a pesticide applicator, you must take responsibility for reducing pesticide risks to honey bees. This can be done by doing the following things:
- Follow the pesticide label. Many labels contain bee hazard statements under the PRECAUTIONARY STATEMENTS (Complying with the label IS the law, after all!)
- Use Integrated Pest Management (IPM). IPM includes a combination of cultural, mechanical, biological organisms and pesticides. If pests cannot be managed by a combination of IPM strategies, a pesticide application may be necessary.
- Communicate with beekeepers near sites that require pesticide application. Driftwatch is a useful tool to help identify hive locations
- Register for DriftWatch to locate hives. (Informational Brochure).
- Know if there is an established RT25 for the pesticide you want to use. This is the residual time for 25% mortality of a hive based on a foliar application. It is assumed that if no more than 25% of the hive is affected, the hive will recover. More information and the data available for active ingredients can be found HERE
Information on Colorado's State-managed Pollinator Protection Plan (MP3) is available HERE.
